hey Jim ... welcome to T-shirt Forums ...
some questions:
how many shirts are you planning to produce per design?
What type of body/fabric, and what type of ink?
are you seeking
DTG or screenprinting or some type of heat transfer?
and how are you going to bring your site traffic?
what geographic region are you in?
There are a lot of shops here in Southern California who could help
with everything but the fulfillment.
